EXPLOSION-ENGINE.

SPEGIFIGATION forming part of Letters Patent No. 663,106, dated December 4, 1900. Application filed December 8,1899- Serial Ila. 739,732. (No model.)

of which the following is a specification.

My invention relates to explosion-engines, and has for its object to produce a means for controlling the said engine from a rotating part thereof. 7

In the accompanyingdrawings I have shown a gas-engine in which my invention is embodied, it being understood, however, that my invention is not limited to the construction shown nor to the idea of controlling gasengines only.

In the accompanying drawings, Figure 1 is a side elevation, partly in section, of an engine embodying my invention; and Fig. 2 is a section of Fig. 1 on the line IIII thereof, the said figure likewise showing the line I I upon which the section of Fig. l is taken.

In the drawings, ais a suitable cylinder, and b a suitable piston working therein, whose rod 0 is connected to a crank 61 u pon the main shaft of the engine. This main shaft of the engine projects outside of the engine-casing and is provided with a flywheel f. The shaft 6 passes freely through a stationary sleeve 9, upon which is hung a freely-rotatable cam h. This cam h is recessed and is shown as provided with a plurality of traveling bevel pinions or gears 'i, which are carried upon and rotate freely upon pintles carried by the cam. The term traveling is here used in the sense of a bodily movement of translation as contradistinguished from a mere rotation of the pinions on their axes. A rotating or movable bevel-gear j is shown as keyed to the shaft 6 and meshes with the bevel-pinions i.

- The sleeve g likewise carries a freely-movable gear or sleeve 70, which carries a normally stationary bevel-gear Z, which meshes with the bevel-pinions 2' of the cam-wheel. A suitable exhaust-valve rod m or other-controlling part is operated by the cam h after the normal manner of an explosion-engine. The gear is normally held stationary by a rack 0, which meshes therewith and which may be rigidly, but adj ustably, held in place on the engine-casing by a set-screw 10 or other suitable device,which will be readily understood gears ij 1, to rotate once during every two revolutions of the crank-shaft c. When it is desired to reverse the engine, the said screw 10 maybe loosened and the rack 0 given a longitudinal movement to move the cam h. It will be obvious that other means may be employed to move the cam to effect the reversal.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s

1. In an explosion-engine, the combination of a governing-valve, a shaft a cam for operating the governing-valve and an epicyclic gear for rotating the cam comprising in its structure a traveling wheel or gear 7; for rotating the cam and a fixed gear land a rotatable gear carried by the shaft and engaging with the said traveling wheel or gear.

2. In an explosion-engine, the combination of a governing-valve, a shaft a cam for operating the governing-valve and an epicyclic train for rotating the cam comprising in its structure a traveling wheel or gear for rotating the cam and an adjustable gear fixed upon some stationary part of the engine and a rotatable gear carried by the shaft engaging with the said traveling wheel or gear and means for adjusting the adjustable gear to shift the cam to effect a reversal of the engine.

3. In an explosion-engine, the combination vofja suitable main shaft, a valve for governing the exhaust from the cylinder, a cam 72. for operating the exhaust-valve and provided with a bevel-gear and means for driving the said cam, comprising a stationary gear fixed to the frame of the engine and meshing with the gear of the cam and a rotatable gear likewise meshing therewith and driven from the main shaft of the engine, substantially as described.
